BOTTIJE-WASHING MACHINE.

Application filed September 13, 192 1.

My invention relates to new and useful inrproveinents in bottle washing machines, and particularly to that class employmg the sprocket wheel actuated chaln oi bottle conveying cups.

With the machines now in use, it is nece sary to remove the bottles from the cups by hand after passing through the washing and rinsing apparatus, which operation requlres many workers and obviously necessltates the expenditure of considerable tune and money.

It is the object of my invention to overcome this ditlicnlty, and to this end I provide a chain or bottle conveying cups each oi? which when it reaches a predetermined point, will automatically turn upon a pivot and discharge the washed bottle and return to its upright position.

Another object of my invention is to overcome the possibility out the bottle conveying chain sliding up and off olf the sprocket wheel.

With. the above and other objects in view which will appear as the description proceeds, my invention consists in the novel fea tures herein set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

lteii'erring to the drawings, in which numerals oi? like character designate similar parts throughout the several views,

F 1 is a plan view oi my apparatus showing a sprocket wheel and cup tilting tracks.

Fig. 2 is a side view oi the wheel, showing the lug retaining groove and the cup lug with relation thereto.

Fig. 3 is a detail View oi one or the cup pivot links.

Fig. 1 is a plan view of a chain of cups showing the lug on the wheel engaging cups, and the pivot links in use.

Fig. 5 is a side view 01' Fig. a.

Fig. 6 is a section taken on line 6-6, Fig. 1, showing the cups inverted, and

Fig. 7 is a view taken on line 7-7 of Fig. 4c.

Tn the drawings, 1 designates a power driven sprocket wheel oi the usual type, at one end of the apparatus having cup engag ing recesses 2 and a flange or chain supporting member 3. 4; represents a chain of hottle conveying cups which consists oi a series of vertically arranged cylindrical cups 5, preferably flaring toward their tops to re- Serial No. 737,531.

ceive the bottle necks :3, and being provided with laterally disposed bearings t3 integral therewith, as shown in 1 and 7. l-ltt the top ot each cup 5, T provide a groove 7, extending circumterentially thereof, which will be referred to later. This chain of cups l may be supported by any desired means.

8 represents my novel pivot link, co1nprising a hook member 9 at one end and a corresponding hook receiving loop 10 at the other. Tntern'iediate the members 9 and 10 a cylindrical bearing member 11, provided with an integral flange 12. This link is adapted to be inserted in the bearing 6 of the cup 5 until the flange 12 abuts the end of said bearing, as shown in Fig. l, and a removable collar 13, having a set screw 141 therein slipped on and the set screw tightened.

After the links are arranged in the bearings of all or the cups, the hook member 9 of each is inserted in the loop member 10 ot the adjacent cup as shown in Fig. 1, so as to form two rows in the single chain.

On the inner or wheel engaging row of cups, T provide lugs 14 integral therewith and extending partially around each cup, and adapted to engage a groove 15 in the wheel 1, to prevent the chain tron] rising on the said wheel.

16 represents a *ies of cup guides comprising three rails arranged side by side at a predetermined location on the apparatus, and extending longitudinally for a portion of their length, then being bent outwardly and downwardly and back again to their longitudinal position. These tracks or guides are adapted to engage the grooves l of the cups 5, before referred to, and as the cups approach the bent section they will turn on their pivots 11, and be gradually inverted as shown in Figs. 1 and 6, discharging the bottles and then return to their original upright position.

The ope 'ation oi my invention is obvious, the bottles 5 are inverted and their necks inserted in said cups 5, as shown in dot-ted lines in Fig. 5, and are conveyed by the chain and sprocket wheel through a washing and rinsing apparatus (not shown) which may be oi any suitable type. its the wheel 1 turns, it gradually brings the cups bean i up; the washed bottles into nnent with the guides 16.. which, as before described,

tilt the cups to discharge the bottles as the till cups reach the bent portions. its the chain moves onward the cups are returned to their original upright positions on the chain.

From the foregoing, it is believed'that my invention may be clearly understood with out further description, and in closing it may be stated that numerous changesmay be made in the details of my device without departing from the spirit of the invention as disclosed in the appended claims.

What I claim and desire to secure by Letters, Patent is LA bottle Washing machine including a chain of bottle; conveying cups, a sprocket Wheel for driving said chain, a groove around the periphery of said Wheel, said cups being provided With lugs adapted to engage said groove, laterally extending bearings on said cups, pivotvlinlrs. adapted to be inserted in said bearings,.said cups being provided with grooves extending circumierentially of the tops thereof, guides adaptedto engage said cup grooves anditurn said cups on said pivots for dischargingthe washedhottles, said guides also serving to return said cups to their. original upright positions.

A bottle Washing machine including a chain of bottle conveying cups pivotally mounted to rotate onthe links oi? said chain at an angle to the line of movement 01 said chain, means for driving said chain, and means for tilting said cups for discharging the bottles.

' 3. In combinationwvith a bottle washing machine, aconveyor chain consisting of a plurality oflinks, a portion of each of said links forming a swivel, a plurality of bottle conveying cups each being provided with a bearing adapted to engage and. rotate on said: swivels, means for driving. said chain, andineans tortilting said cups 101' dischargingthe bottles.

4, In combination with a bottle Washing.

machine, a cmivcyor chain consisting oi a plurality of links, a portion ol' each oil said links forming a short shaft, a plurality ot ixittleeonveying cups, each being provided with a bearing member adapted to engage and rotate on said shafts, each of said cups being alternately disposed on said chain With relation to the adjacent cup, means for driving said chain, and means for tilting said cups for discharging the bottles.

5. ln combination with a bottle washing machine, a conveyor. chain consisting oi a plurality of links, a portion of each of said linlrs 'iorining a short shaft, a plurality of bottle conveying cups, each being provided 'witha bearing member, an d a groove aroi'lnd upper enrrernity, each oi? said bearing inei'nbers beingadapted to engageand rotate on the short shaft oi? one of said links, a phirality of guide rails adapted to register with and engage said grooves in the cups, saidrails being bent at predetermined points for tiltingsaid cups to discharge the bottles, and means for driving. saidchain.

6. A bottle washing machine including a chain of pivotally mounted bottle conveying cups, a sprocket \vheel tor driving said chain having a groove around its periphery, certain ot. ,aideups having lugs :lor engaging said groove, whereby said chain is prevented from moving axially oi saidwheel.

T. A conveyor tor bottle washing ma ci'iines,comprising a chain of links, each of said links being provided with connecting elements at its opposite ends, a short shaft interposed between said elements, and a plurality of bottle collveying cupsneach being provided with a bearing,member adapted to engage and rotate onthe short shafts ot said links.

In testimony whereof I aliiz; my signature.
